Which structures constitute the throat region?

• A. Oropharynx, tonsils, nasopharynx
• B. Esophagus and stomach
• C. Larynx and trachea
• D. Nasal cavity and sinuses

Answer: (A)

Think of the throat as the pharynx, a muscular tube behind the nasal and oral cavities that serves as a passage to both the digestive and respiratory tracts. The pharynx has distinct parts: behind the nose is the nasopharynx, and behind the mouth is the oropharynx. The tonsils are lymphoid tissue located in the oropharynx and are commonly considered part of the throat region. So, the structures that make up the throat region are the nasopharynx, oropharynx, and tonsils. The other options refer to areas outside the throat: the esophagus and stomach are below the pharynx in the digestive tract; the larynx and trachea are part of the airway but not the throat itself; and the nasal cavity and sinuses are above the throat in the nasal passageways.
